I have a list of lists. it's length (the number of sublists it
The length of each of the sublists is arbitrary, too. So I have this
list of lengths.
I want to obtain the list of all combinations of one element of each
sublist, bounded by &&. This will be a list of 120 elements, each of
them with 4 components. I define a delayed formula, and apply Array to
it (the characters printed as bold are subscripts in the Mathematica
Since the length of des varies, I would have to define cond each time.
I would like to make a definition for cond that would adapt to these
I arrived to this solution, which is not rejected by Mathematica, but
does not work, either.
In fact, I quit the kernel and rerun all the cells except the one
written here as In. If not, the definition for cond4 remains as it
was. I was not able to clear cond4 individually.
Thanks very much for anything you can suggest.
